performance-difference on Solaris between using ZFS
on a partition, or a whole disk. FreeBSD is happy with either.
The two alternatives you mentioned were:
ZFS over GELI over disk
and
ZFS over GELI over ZFS over disk
While ZFS wouldn't get the raw disk in setup #1, the left-most ZFS wouldn't

There are few different ways to set-up geli with ZFS. I just want to get
some opinions (benefits and disadvantages) about the below two options
*First option*: (most commonly encountered set-up)
Have geli on the block device and ZFS on top of the geli
and the last minute transactions
are important. Using a zpool over geli over a zvol. I'd like to know if
during shutdown the kernel flushes all zfs files caches in order so
these last minutes transactions won't be lost. The unmounting order is
far from obvious (zfs over geli over zfs) and i
be lost. The unmounting order is
far from obvious (zfs over geli over zfs) and i wonder if such a scheme
will succeed. I can't afford losing the last transactions of my home dir
every time i shutdown my laptop;)
If it's a normal clean shutdown, then yes, all pending transactions
